DUPLEX COOKING ATTACHMENT FOR sTovEs.

Application led November 10, 1924. Serial No. 748,841.

To all whom z't may concer/n.'

Be it known that I, -VIRGIL DE VoT PORTER, a citizen of the UnitedStates of America, residing at Wylam, in the county of Jefferson andState of Alabama, have invented certain new and useful Improvements 'inDuplex Cooking Attachments for Stoves, of which the following is aspecification.

My invention relates to a duplex cookingv attachment for liquid andgaseous burning stoves, and has for its object to utilize one burner toheat two vessels for cooking there- 1n.

My invention contemplates the provision of a anged cooking vesselsupport adapted to set on the stove top with its flange at one endadapted to nearly surround the burner that is lighted and to direct theproducts of combustion from the burner laterally through a duct to aspider adapted toy receive the second vessel to be heated, such spiderbeing designed so as to permit the free escape of the products ofcombustion while causing them to pass crosswise of the bottom of thesecond vessel and thus to heat the latter most eiiiciently.

vessel illustrated in full lines, and the second vessel in dotted lines.

Fig. 2 is a side elevation of the attachment.

, Figs. 3 and 4 are cross-sections taken res `ectively on the lines 3 34and 4-4 of Similar reference numerals refer to similar parts throughoutthe drawings.

In the embodiment of my invention illustrazted in the drawings, I show atypical gas stove top 1 having a burner 2 and I mount my attachment onthe top with its marginal iiange 3 at one end surrounding the spaceabove the burner 2 except on one side where the flange mer es into theconvergent-side walls 4 of theieat duct, which walls 4 in turn mergeinto the curved flange 5 of the spider support for the secondary cookingvessel 6. The flange is formed with a wide horizontal top flange 7 whichforms a complete eye adapted to receive and4 be closed by the primarycookingvessel 8. At one side this iange merges flush into the top 9 ofthe lateral heat duct through which the products of .combustion iowbetween the side walls 4 to the spider support'for the secondary cookingvessel. This spider support comprises a series of strai ht divergentribs 10l which extend from w ere they join the top wall 9 of the ductacross the vessel support and at their outer ends are connected to theHange 5. above the level of the top 9 and the flange 5 and dependsubstantially below the under lsurface level of the top 9. This thusforms a raised spider support which will permitthe products ofcombustion passing through the duct to flow transversely across vunderthe secondary vessel and freely -escape on all sides about it so thatregardless of thev size of such vessel it is not possible forit to'chokeand put out the burner 2. The convergent side walls 4 of the heat ductconcentrate the heat towards the center of the spider an'd the ribs tendto carry it across under the vessel;

In operation, the primary cooking vessel 8 should be of such size as toclose the eye above the burner and cause all of the products ofcombustion to be diverted laterally through the tapering duct to thedivergent channels between the spider ribs that support the secondarycooking vessel and thus the heat from one burner can be most ellicientlyused for cooking in two vessels.

Though I have described with great particularity the details of theembodiment of the invention herein shown, it is not to be construed thatI am limited thereto, as

'changes in arrangement and substitution of equivalents may be made bythose skilled in the art without departing from the invention as definedin the appended claims.

Havin thus described my invention, what I c aim as new and desire tosecure by Letters Patent, is

1. An attachment for gas and oil burning stoves, comprising a shallowmarginally flanged casting having two eyes adapted to be disposed abovetwo adjacent stove burners, the eye over one burner being un- The ribsrise obstructed and adapted to be closed by a cooking vessel, the eyeover the other burner having integral divergent shallow cast ribsextending transversely from side to side thereof and having their upperedges lying `in a plane raised slightly above the top level of thecasting, the ribs providing uninterrupted heat channels which divergefrom the line of approach ofthe products of combustion flowing between.the side flanges of the casting from the closed to the ribbed eye.

V2. An attachment for gas and oil burning stoves according to claim 1,in which the side flanges of" the casting are drawn together to contractthe passa e between the eyes symmetrically and sai ribs are arranged todivide the products of combustion delivered to them from the contractedthroat of said passage into substantially equal parts. Y s

'mony whereof I affix my signature.
